Huh? You've miseed something. Multiple instances of a flag are
often used by programs; debugging flags are often done this way.
For instance, each -d raises the debugging level by one. Fixing
getopt in the manner you suggest would break these programs.
Your script command above should be exactly the same as running
"script -a -b -b -c"; your program is just going to have to handle
this.
